CAMP-STOOL.

SPECIFICATION forming part of Letters Patent No. 647,171, dated April10, 1900.

Application filed September 25, 1899. Serial No. 781,680. (No model.)

To aZZ whom it may concern: G designates a hand-wheel pivotally at- 50Be it known that 1, JAMES A. WILEs, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Camp-Stools; and- I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanyingdrawings, and

to the letters of reference marked thereon,

which form a part of this specification.

This invention relates to camp-sto0ls and possesses the novel featureshereinafter described and claimed.

In a detailed description of the invention reference is made to theaccompanying drawings, of which- 7 Figure 1 is an elevation of the stoolin an opened position; Fig. 2, an elevation of the stool closed; Figs. 3and 4:, top and bottom plan views, respectively, of the friction-block.Fig. 5 is a detached plan View of the hand- Wheel for manipulating thelegs. Fig. 6 is a section through the friction-block on the line a; asof Fig. 3.

In the following specification similar reference characters willindicate corresponding parts in the several views of the drawings.

A designates legs which lie parallel with each other when the stool isfolded, as in Fig. 2, and cross each other when the stool is opened, asin Fig. 1.

B is a flexible seat or canvas which has a seam O around its edge thatincloses a chain c, which passes through openings in the upper ends ofthe legs. The said canvas is therefore free from any direct connectionwith the legs and is free to fold and spread out when the legs areopened or closed.

D is a friction-block against which the legs bind when opened. Thisblock has four openings E, through which the legs pass. The saidopenings have tapering sidesE and E, against which the legs bind whenopened, as in Figs. 1 and 6.

seat, the said legs bind against these surfaces in such a manner thatlocks them firmly.

When weight is placed on the tached at its center to the axis-F of thefriction-block by means of a bolt D. This wheel has openings G, throughwhich the legs pass. In moving the said wheel G in opposite directionsthe legs are all simultaneously opened and closed, as the case may be.These opera tions may be donewith one hand grasping the hand-Wheel toturn it,while the other hand lightly holds the friction-block. The wheelG islimited in its movements in opposite directions by a pin I, whichprojects from the lower face of the friction-block D and enters one ofthe openings G. The said opening G has opposite slots J, into which thepin I enters at the limit of either movement.

H is a flexible connection, such as a rope or chain, between the centerof the seat B and the friction-block D to hold said block up when thelegs are closed up.

K are pins which gage the proper position of the friction-block when thesame is in an operative position.

In folding the stool, as in Fig. 2, it is only necessary to catch holdof the friction-lolock and lift the stool from the floor or ground, whenthe legs immediately assume perpendicular positions when the hand-wheelis turned.

I claim as my invention- 1. In a camp-stool, the combination of legs, afriction-block having openings therein with tapering sides E and Eagainst which the legs bind when opened, and a hand-wheel pivoted tosaid friction-block and adapted to open and close the legs, as hereinshown and described.

2. In a camp-stool, the combination of legs,

a flexible seat, a chain inclosed in the edges 1 of said seat andpassing through openings in the upper ends of the legs, a friction-blockhaving openings therein through which said legs pass, the said openingshaving tapering sides with which the legs engage when in slantingpositions, a hand-wheel pivoted to said friction-block by means of whichthe legs are opened and closed, and a flexible connec tion between theseat and said friction-block, substantially as described.

3.
